Jesus had finally (at the age of 33!) left his pre-dominant father and
then spent 10 years in the Himalayas for further training, he visited
the planet MOX in order to cure a violent flu he had caught.

is where he left his hot water bottle behind.

From the slightly dirty, but holy Himalaya-water, which remained in the
hot-water bottle, emerged two new organisms, Yeti and Kneti.
